Disbondment and Adhesion Failure

 

Coating Disbondment on PipeAdhesion failure, causing disbondment of paints, coatings, sealants and other surface treatments can cause significant problems both during and after manufacture. 

 

 

 

 

 

Careful analysis across a failed interface is required to diagnose the failure, and to understand  where the failure is occurring. This could be between layers, such as between a primer and a paint, or within a single layer such as within a polymer laminate tie-layer.

 
 

 

 

Surface contamination is a common cause of adhesion failure, but factors such as an unsuitable choice of coating chemistry, migration of mobile species into (or out of) a layer, or exposure to unexpected environmental conditions can also result in delamination effects.

Surface Contamination

Investigation of surface chemistry and characterisation of the materials involved is an important part of solving any issue.
